Do you have anti lag installed on your InfinityMU client? Maybe it's because of that. Alternate ways to fix is to have a fresh installation of the IMU client and try again.
Please provide the operating system that you are using. What version of windows is it?
You can also check the logs of the game client within the folder and post the log file here. Maybe any mods or [MENTION=1]RESiSTANT[/MENTION] himself will assist you.
